Can't Install Windows Bootcamp, HELP!

Hello, I can't seem to install windows 7/8 via Bootcamp. I have used various Images including the official ISO, and have created bootable USB/DVD's via my PC using Windows 7 USB/DVD Download Tool. Yet I always end up with the same error once in installation: " Windows cannot install required files. The file may be corrupt or missing. Make sure all files required for installation are available, and restart the installation. Error Code: 0x8007057 " (I also get the same error on VituralBox UNLESS I am using the official ISO and then it installs flawlessly, but I have used the official ISO with Bootcamp and No Luck.)

P.S, I was told to "Unlock" the "Create Windows 7 install disk" and then use the official ISO (That worked with VituralBox), Would that work?

Thanks In Advanced.
